PROBLEM: pygtk progress bar

bendeco13 · 04-03-2005, 09:32 PM

I'm really new to python and pygtk...
Everytime this 'StartRemove' class is called, it's supposed to popup a progress bar with some other labels. The problem is: the progress bar, labels, etc., don't show up until the progress gets to 100% or progbar.set_fraction(1). I don't have a clue as to whats causing this...

Here's what I have.

Code:

class StartRemove:

    def callback(self, widget, data):
        if (data == "stop"):
            print data

    def __init__(self):
        global filelist, message, numaffected

        if (recrusive == False):
            findcommand = "-maxdepth 1 "
        else:
            findcommand = ""

        filelist = os.popen('find "' + directory + '" ' + findcommand + '-name *.mp3 | sort').read()
        filelist = filelist.splitlines()
        numfiles = len(filelist)
        if (numfiles == 0):
            message = "No .mp3 Files Were Found In:\n" + directory
            ErrorBox()
        else:
            self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
            self.window.set_title("IH8id3 - Progress")
            self.window.connect("destroy", self.callback, "stop")
            self.window.set_border_width(5)

            main_vbox = gtk.VBox(gtk.FALSE, 0)
            vbox = gtk.VBox(gtk.FALSE, 0)
            vbox2 = gtk.VBox(gtk.FALSE, 0)

            self.window.add(main_vbox)

            align = gtk.Alignment(0.5, 0.5, 0, 0)
            vbox.pack_start(align, gtk.FALSE, gtk.FALSE, 5)

            progbar = gtk.ProgressBar(adjustment=None)
            progbar.set_fraction(0)
            progbar.set_orientation(gtk.PROGRESS_LEFT_TO_RIGHT)
            align.add(progbar)

            separator = gtk.HSeparator()
            vbox.pack_start(separator, gtk.FALSE, gtk.FALSE, 5)

            label1 = gtk.Label("Starting...")
            vbox.pack_start(label1, gtk.FALSE, gtk.FALSE, 5)

            main_vbox.pack_start(vbox, gtk.FALSE, gtk.FALSE, 0)

            label2 = gtk.Label("Files Scanned:")
            label2.set_justify(gtk.JUSTIFY_LEFT)
            vbox2.pack_start(label2, gtk.FALSE, gtk.FALSE, 0)
            label3 = gtk.Label("Files Affected:")
            label3.set_justify(gtk.JUSTIFY_LEFT)
            vbox2.pack_start(label3, gtk.FALSE, gtk.FALSE, 0)
            label4 = gtk.Label("Version 1:")
            label4.set_justify(gtk.JUSTIFY_LEFT)
            vbox2.pack_start(label4, gtk.FALSE, gtk.FALSE, 0)
            label5 = gtk.Label("Version 2:")
            label5.set_justify(gtk.JUSTIFY_LEFT)
            vbox2.pack_start(label5, gtk.FALSE, gtk.FALSE, 0)

            frame1 = gtk.Frame("Stats:")
            frame1.add(vbox2)
            main_vbox.pack_start(frame1, gtk.FALSE, gtk.FALSE, 0)

            button1 = gtk.Button("Stop")
            button1.connect("clicked", self.callback, "stopbttn")
            button1.set_border_width(5)
            main_vbox.pack_start(button1, gtk.FALSE, gtk.FALSE, 0)

            self.window.show_all()
	    self.window.activate_focus()

	    #self.progbar.configure(0, 0, numfiles)
            numaffected = 0
            count = 1
	    
	    import time

            for i in filelist:
		time.sleep(.2)
                percent = float(count) / numfiles
		print percent
                progbar.set_text(str(int(percent * 100)) + "%")
                label1.set_text(i)
                label2.set_text("Files Scanned: " + str(count))
                label3.set_text("Files Affected: " + str(numaffected))
                label4.set_text("Version 1: ")
                label5.set_text("Version 2: ")
                progbar.set_fraction(percent)
                count = count + 1

            label1.set_text("Finished")

            button1.set_label("Ok")
            button1.connect("clicked", lambda w: self.window.hide())

Pleeeeeeaaaaaseee Help.
Thanks in Advance,
Bendeco

I'm sorry... but what does nvm mean (nevermind?)

Ok I fixed it.
Obviously, the window needs to be redraw everytime the progress gets updated.
Here what I added...

Code:

while gtk.events_pending():
    gtk.mainiteration()

so it looks like this...

Code:

            numaffected = 0
            count = 1
	    
	    import time

            for i in filelist:

		while gtk.events_pending():
		    gtk.mainiteration()
                
		time.sleep(.2)
                percent = float(count) / numfiles
		print percent
                progbar.set_text(str(int(percent * 100)) + "%")

Hope this helps anyone else who has this problem...
